Compressibility & Effective Seals

Assembled housings or enclosures must ensure adequate gasket compression to provide the required level of seal. PORON® Polyurethane materials have a relatively flat compression force deflection curve. This compressibility enables the load to remain within required limits while accommodating a larger range of compressions. This widens overall design limits beyond the capabilities of many materials, such as elastomers. PORON® foams will not take a set or relax, thus maintaining an effective seal over the life of your product.
